JD Jet Kit...Forget the Washer Mod!!!
My 06 KLR 650 never ran well. Always lean, unpredicable idle speed and hard cold start. I did the washer mod last year, and it helped. But it still wasn't right. I ordered the JD jet kit and installed as directions suggested. Since mine is a stocker and mostly run below 4000 feet, I used the blue needle set on the second notch, with a 160 main jet. The stock jet was a 148. I drilled the slide with the drill provided. The kit comes with a selection of jets, 2 needles and the prescribed drill bit. I had it done in under 30 minutes.
Results are faster cold start, great idle, less popping on decel, no surge and more pull, especially above 4000 rpm.
This is a terrific mod and I highly recommend it.
